T0 ALL WI-IOM IT MAY CONCFRN:

Beit known that I, GEORGE R. MOORE', of Iiyonls,lin the county of Clinton, and State of Iowa, have invented certain new and useful Improvements in Corrugating-Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object ofmy invention is to provide a machine for making diametrical eorrugations upon sheet-metal cylinders, of several feet in length, and upon any place in their whole length which may be desired. l i

Machines for doing this kind of work upon short lengths of cylinders, or upon places near the ends of long cylinders, are old and very common, and known in tin-shops as beading-machines. My invention provides for extending the length of arhors,'and the support of the same, in this general kind of a machine, se that Without great expense cylinders from six to teu feet long can be corrugated or beaded2 at any place in their whole length. My invention provides ,also for a convenient handling and holding ofthe cylinders in the required process; also, for a screw or spiral eorrugation, when desired.

i A is the ordinary standard, upon which the machine is bolted down upon the bench B. C and D are special movable standards or movable supports, in this ease pivoted to the bench, and attached to each other'by rods, a a, of such length as to alternate their positions and secure one-as an upright support to the machine, when the other lies in a horizontal position upon the bench. E and F are the ordinary arms of the framework of the machine, and Gris a special extension or lever support tothe arm F, to which, in this case, it is bolted with small bolts, b. Upon this extension-lever, G, there are rollers, I-I II, which serve as a saddle to carry the cylinder easily while rotating in the machine. l i

The cylinder to be corrugated is passed into the machine, so as to enclose the usual arm F, the extensionlcver G, with the saddle-rollers H H, and one ofthe corrugating-rollers, I, and its arbor, with which the crank ofthe machine is firmly connected. To do this, the movable standard, G, is turned down to a horizontal position, and the cylinder placed into the machine as far as to D, when D is turned down, and C brought inte an upright position, where it remains until the work is donc, The upper corrugating-roller, J, is forced down by the armscrew K, so as toindent the cylinder as much as may bo desired, when the crank is turned and the corrugation accomplished. i

The gauge L may he used in the ordinary way, also in connection with the screw-guide O, when that is pressed down into the thread upon the lower arbor. l In this machine the cog-wheels Q, and R are :not of equal number of cogs, but Q revolves its arbor and roller faster than R, and thus, by rubbing upon the metal slightly, hurnishes a part of the corrugation. The gauge-rods M M Jare bolts as well, tostrengtheu the machine, and are designed and applied for this double purpose of being a part ot the substantial framework, and at the same time serving as gauge-rods. S is a circular or pronged brace, of sufficient width, or of Isuch shape as to allow any cylinder to be corrugated to pass under it, and it is applied to give additional strength to the upper part of the framework of the machine, to which it is bolted or made fast at C, and also to the bench at cl d.

IIaving thus fuilv described my invention, what claim therein as new, and desire to secure by Letters arranged substantially as described. i
